Be it known that I, FnANoIs H. GOOD, a

citizen of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented anew and usefulImprovement in Carpet-Cleaners, which improvement is fully set forth inthe following specification and accompanying drawings, in whieh- Figurel is atransverse section of a carpetcleaner embodying my invention. Fig.2 is a side elevation thereof partlyl broken away. Figs. 3 and 4 areenlarged views of detached portions. I

Similar letters of reference indicate courresponding parts in theseveral figures.

My invention consists of a carpetcleaner having a cylinder' or drumwithin which are mounted lfters or elevators which have eccentric axes,so that they overturn at intervals,or when they reach a certain point orheight, and thus throw the carpet forcibly forward and downward to thebottom of the drum.

It also consists of stops for limiting the degree of rotation of thelifters.

It further consists of locks or latches for preventing rotation of thelifters until they .to which journals or gudgeons are attached,

the latter being mounted on a stand or hangers, as desired, theperiphery of the heads being polygonal, whereby the periphery of thedrum is polygonal or many-sided. 'With in the drum are elevators B,which are formed of suitable vanes or blades extending parallel with theaxis ofthe drum and pivotedy at intervals to the heads or ends ZJ, saidvanes or blades being yof slatted or Open work, so as to permit the dirtand dust to fall therethrough. The elevators have their axes eccentric,so as to overturn when they reach acertain point, the overturning beinglimited by stops c, secured to the heads b, and in order to support theelevators immovably at other points the heads b areprovided with stopsd,against which the said elevators abut,`it being noticed that the stopsc d for each elevator are secured to the heads at such places that theyare in front of `the elevator in the direction of rotation.

- C represents a pulley which is secured to the periphery of the drum,and may be formed of segments secured thereto, said pulley being adaptedfor a band or belt driven by any suitable power. l

The operation is as follows: The carpet is introduced into differentparts of the drum through the doors or openings thereof, thelatter beingafterward duly closed. Power is then communicated to the drum, and as itrotates the first elevator resting against the stop c,eoniing in Contactwith some of the carpets, raises the same until it approaches thehighest point, where said elevator, owing to its eccentric axis,overturns and throws the carpet forcibly forward and downward to thebottom of the drum, causing it to be beaten against the slattedperiphery, the elevator now resting on the other stop, a, whereby it isprevented from overturning to improper eX- tent, or standingvertically.` Another load of carpets is meanwhile in such position thatthe second elevator takes hold of the same and begins the elevation justabout the time that the first load has been thrown off and around fromtherst elevator. Now, when therst load strikes the bottom, it does it insuch manner as Ato givean impetus and powerto the drum, thus assistingthe rotation thereof, and as only one load is being raised the engine'or motor is relieved of double work. The next elevator then raises theload previously Athrown down, and meanwhile the second elevator hascleared itself, the operations being repeated -until the work iscompleted, the dirt, dust,

8tc.,being completely beaten from the carpets, leaving then clean andbright. Another advantage ot' the use of the elevators is such that thecarpets are kept separated, whereby they are more readily cleaned.Again, the carpets are turned or overturned and drop or fall withoutrolling on the periphery of the drum, thus avoiding the abrasion due tosuch rolling. Furthermore, when the carpets fall they strike angularfaces of the drum,and are thus subjected to greater beating andrcleaning' action than if such faces were round. Y In Figs. 3 and L lshow means for locking th elevators until they reach a required height,when they are relieved and permitted to over- Ioo turn. For thispurpose. I employ springlatches D, Which are Withdrawn by the action ofcams E on the frame or hanger ot' the bearings of the drum, so that theelevators may be released and permitted to turn, after which they assumetheir normal positions and the latches 11e-engage, vso as to hold theelevators lirinly for advancing the carpet in the man ner hercinbeforestated. The latches or bolts D are passed through the pieces b, andtheir shanks or stems D engage with the cams E, above mentioned, wherebyWhen the elevator has reached the proper height the stein of the latchthereof comes in contact with the cams and causes the latch or bolt t bewithdrawn from the elevator, and thus the latter is permitted tooverturn and drop its load of carpet, the latter falling to the bottomof the drum7 as hereinbefore stated. As soon as the stem of the latchclears the cam the bolt returns to its normal position, so as to preventaccidental overturning of the elevator as it again rises with the drum.The band Wheel or pulley secured to the periphery of the drum acts as abrace,serving to strengthen the saine.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is

l. A carpet-cleaning drum having Within the same a rotatable lifterWhose axis is eccentric, and a stop for each end of the lifter, bothstops being located in front of the lifter in the direction of rotation,substantially as and for the purpose set forth.

2. In a Garpetcleaner, a drum, in combination With a latch engaging withthe lifter of the drum, and a cam engaging With the latch forwithdrawing said latch from the lifter, whereby the lifter isautomatically released, substantially as and for the purpose set forth.

8. In a carpet-cleaner, a drum having alifter, and stops for each end ofthe lifter,located in front of the same in the direction of rotation, incombination with a latch and cam, said latch engaging with the lifterand said cam .operating the latch, substantially as and for the purposeset forth.
